Summary: The LiNi0.5Mn0.3Co0.2O2 (NMC532) cathode surface was coated with LLZO using the citric acid-aided sol-gel technique. A thin coating layer was obtained and the formation of LaMO3 was observed during high-temperature annealing. The electrochemical performance of the coated samples was improved, with higher capacity retention and lower interface resistance.

Summary: This study successfully synthesized V-substituted Na0.67Fe0.5Mn0.5O2 cathode material with improved electrochemical performance, and investigated the effects of V-substitution on its chemical composition, crystal structure and morphology, as well as the modification mechanisms on the enhanced electrochemical properties. The results showed that introducing V ions into the lattice of Na0.67Fe0.5Mn0.5O2 crystals significantly improved its rate capability and cycle stability, mainly due to the enhanced Na+ diffusion rate and structural reversibility.

Summary: A two-dimensional bilayered V2O5 center dot nH2O nanomaterial with Zn2+ intercalation was synthesized via a facile sol-gel method combined with vacuum freeze-drying. The microstructure and surface morphology were characterized by XRD, EDS, XPS, and SEM measurements. The Zn2+ intercalation resulted in the formation of a layer-by-layer stacked sheet-like morphology and promoted the presence of V4+ states in V2O5 center dot nH2O. Compared to the pure sample, the V2O5 center dot nH2O sample with Zn2+ intercalation showed improved rate capability, cycling stability, Na+ diffusivity, and reduced electrochemical reaction resistance.

Summary: The calcination temperature significantly affects the physical and electrochemical performance of Na4MnV(PO4)(3)/C composites. The surface area, carbon disorder, Na+ diffusion coefficients, and electrochemical performance are greatly influenced by the calcination temperature. Additionally, the optimal calcination temperature for the composites is found to be 750 degrees C, resulting in the highest capacity, best rate capability, and cyclability.
